Documentation

Overview

Package ed25519signature2020 implements the Ed25519Signature2020 signature suite for the Linked Data Signatures [LD-SIGNATURES] specification. It uses the RDF Dataset Normalization Algorithm [RDF-DATASET-NORMALIZATION] to transform the input document into its canonical form. It uses SHA-256 [RFC6234] as the message digest algorithm and Ed25519 [ED25519] as the signature algorithm.
